Engineered by Guangdong Dejiyoupin Doors and Windows Co., Ltd., delivering thermal break efficiency, ultra-slim sightlines, multi-point burglar resistance, and CE-certified precision.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. stands at the forefront of fenestration engineering, operating one of the largest intelligent manufacturing hubs in Foshan, China. Certified as a prestigious China Famous Brand by Xinhua News Agency, our factory delivers industry-leading aluminum sliding doors, high-efficiency casements, structural glass sunrooms, and bespoke systems to over 300 tier-one distributors, construction conglomerates, and architectural design firms worldwide.
With an expansive 180,000 m² state-of-the-art production base and an annual capacity surpassing 1,000,000 m², we bridge the gap between high-volume manufacturing output and stringent European building standards. Every sliding door assembly undergoes rigorous mechanical testing and multi-axis CNC tolerance verifications to meet demanding structural, acoustic, and thermal barrier specifications.
From boutique residential developments to high-volume commercial towers, our automated profile extrusion handling, glass processing, and precision assembly lines prevent project supply bottlenecks.

Professional developers and facade engineers evaluate sliding systems far beyond aesthetics. True reliability requires structural wind-load equilibrium, air permeability control, thermal optimization, and frictionless hardware integration.
We deploy continuous multi-chamber polyamide PA66 GF25 thermal break strips within our 6063-T6 virgin aluminum extrusions. Combined with insulated warm-edge spacers, this architecture minimizes thermal conductivity.
Wind-driven rain creates extreme differential pressures across sliding tracks. Our precision-milled multi-tier internal drainage and non-return weep valves ensure zero water backflow.
Expansive glass openings demand supreme inertia moment ratings. Our profiles incorporate reinforced internal web stiffeners to withstand gale-force coastal buffeting without deflection.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. provides comprehensive technical submittals, testing reports, and structural calculations to streamline local authority approvals and project sign-offs.
Tailored sliding door topologies engineered for modern villas, penthouse terraces, hospitality projects, and upscale urban developments.
Featuring an interlock sightline as narrow as 20mm, this system maximizes panoramic natural light while concealing frame tracks within finished walls and floors.

Global developers face tightening embodied carbon quotas (such as the EU Carbon Border Adjustment Mechanism). Future-ready sourcing requires aluminum billets produced using renewable hydroelectric smelters and recycled post-consumer scrap to slash carbon footprints.
Building codes worldwide are mandating near-zero energy consumption. Sliding door engineering is moving rapidly toward aerogel-enhanced multi-chamber cavities, vacuum insulated glass (VIG), and quadruple-sealed air interlocks capable of Passive House certification.
Architects demand completely concealed hardware. Procurement is shifting towards frameless perimeter framing embedded in drywall, combined with IoT-linked climate controls, electromagnetic locking, and voice-automated slide functionality.
To eliminate intermediary margins and project execution risks, top developers and distributors are bypassing trading agents. Direct factory procurement from integrated manufacturers like Guangdong Dejiyoupin Doors and Windows Co., Ltd. ensures factory pricing, verified origin, and coordinated fabrication.
